|
I have 2 computers, fpemud-workstation and fpemud-notebook.
The problem phenomena is notebook can not solve workstation's ip address with samba protocol.
I found through tcpdump it is because workstation doesn't receive samba broadcast packet that sent by notebook.
Is it the hardware problem, driver problem, kernel configuration, sysctl setting or something else?
I can't do further test sine I don't have any other OS.
